Details for BA finish
BA is one of the finish of stainless steel.In fact, it belongs to the mirror surface,but there is not clear like mirror. BA surfaces are produced directly from the steel mills,and it return to achieve brightness bright directly.It refers rolled stainless steel plate after bright annealing treatment,a surface state after a flat.Indeed,BA is just a surface,is in direct annealing process produced surface.
However,because of a steel plant control,testing and product requirements of their different levels,so different surface effects seen appear on the market.Even for the same manufacturer, different time,different shifts production of products,the surface will have some differences,such as surface brightness,surface roughness,etc.But currently does not have a specific predetermined criteria for this,but mainly to see manufacturers positioning and market acceptance.
In China, like TISCO, LISCO, ShuoYang, Austar is a major manufacturer of BA surface.These mills produced by the BA surface with excellent results.not only beautiful surface, but the quality is also high.The main materials are 201,304,430 three type.

Applications for BA fini
Such as automatic washing machine drum, bathroom accessories, lampblack machine, dishwasher, microwave oven, stainless steel pot, stainless steel pot, button batteries, watch shell, mobile phone shell, stainless steel spoon, handrail elevator, auto parts, solar water heaters, medical equipment and so on, we see the bright surface of the stainless steel products.
Also,BA finish is widely used in required a high degree of reflectivity of morehome appliances.small mirrors,kitchen equipment,Washing machine inner cylinder, elevator door decoration, building decoration and other fields etc.
Processing for BA finish
No clear criteria. After cold rolling through bright annealing process, and to temper rolling products, high surface reflectivity. Or mirror-polished surface with a cloth buffing wheel obtained.
